On fastest possible, terran ownz toss...most ppl don't know it cause terran are the underdogs, and aren't used that much in money maps ... bunkers are useless on fastest possible...they don't do much. The best thing to do, as stated by trongamonga, is to rush them...yes...rush...with terran..against a toss... it doesn't seem right...but marine, medic, siege tank, and vessel is the way to go ... trust me... trapping urself in just makes it worse...it gives ur opponent time to mass up the necessary units to bring down ur defense
The terran race is all about PRESSURE...not turtleing...ALWAYS RUSH...
Also, u don't need to mass up factory or mass up barracks... 6 rax and 2 factory and 2 starports should be ok ...
Oh yeah, make good use of ur opponent's choke point on fastest possible...try to trap them in...
If you're good, the game should be over in less than 20 min and won't result in massing units at the end
And remember, this is FASTEST POSSIBLE, not LT...therefore, lockdown is totally useless and shouldn't even bother being researched, Ghosts don't do crap either and shouldn't be built, and the only air units worth getting on fastest possible are the dropship and the science vessel
i will attach a 1v1 replay, it is me (tiger_shark, Terran top middle) vs killmeifucan (toss, top left)... good expert 1v1 replay ... the other ppl are spectators, even though they build up and fool around
